如何创建Java Web Start应用程序的线程转储

// 在Java Web Start应用程序的init()函数中添加线程信息的代码
@Override
public void init() {
    executorService = Executors.newCachedThreadPool();
    executorService.submit(() -> {
        Runtime.getRuntime().addShutdownHook(shutdownHook);
    });
}

// 在Java Web Start应用程序的start()函数中对线程进行监控
@Override
public void start() {
    Runtime.getRuntime().addShutdownHook(shutdownHook);

    monitorThread = new Thread(() -> {
        while(true){
            executorService.submit(() -> {
                while(true){
                    try{
                        Thread.sleep(5000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            });
            executorService.submit(() -> System.gc());
            executorService.submit(() -> System.runFinalization());
            try {
                executorService.submit(() -> Thread.sleep(3000));
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    });
    monitorThread.start();
}
